Adding Digital Certificate in a PDF file using ReactJS - certificate

Is there any library for ReactJS to use for adding Digital Certificate in a PDF file? We are going to develop a system that has a feature that users can sign using their digital certificate so it would be totally paperless documents. I hope someone could help me with this.
Thank you.

It sounds very much like you haven't signed your code.
RIM track the use of some sensitive BlackBerry APIs. This is indicated in the API reference documentation by a lock icon or are otherwise noted as "signed".
Please see the following url for more information about these keys and how to request yours

WS-Security on iphone, is it possible?

I'm new here and I'm facing a problem. I need to know if it is possible to implement the WS-Security protocol with X.509 certificates on a native iPhone application. I haven't found much information on the web, except this information from Apple about security services.
I just want to ask, is it possible? has it been made before?. If it is possible, can you point me in the right direction?.
Thanks in advance.
You should be able to implement this using OpenSSL.
There is a tutorial on The Rare AiR on how you can compile the library for iPhone.
Hope this helps,
Claus
